in reply to decimal to fraction

The same with Perl 6:

Note: nude stands for numerator-denominator.

    > 0.49420098210293.nude (49420098210293 100000000000000) > 0.49420098210293.Num().Rat(1e-15).nude (463051 936969)
    Yay Perl6. Took me a while to figure out the magic incantation, because the Perl6 documentation is nigh incomprehensible. Also, Rat() ignores the epsilon parameter if it's called on a rational. Sometimes, you'd like to find a fraction that's an approximation of another fraction without mashing it down to a float first.
